Dust Collector: Central Air Filtration for Industry
A Dust Collector is a large-scale air filtration system that captures, separates, and removes dust particles and contaminants from the air within industrial facilities.
Its primary purpose is to:
What Is a Catalytic Combustion Dust Collector?
A Catalytic Combustion Dust Collector which is also known as a catalytic oxidizer that is an advanced air pollution control system that removes harmful gases, volatile organic compounds (VOCs) and fine dust particles from industrial exhaust air.
Unlike traditional filtration units, this system uses a catalyst-assisted oxidation process to decompose pollutants into harmless substances like carbon dioxide (CO₂) and water vapor (H₂O) at relatively low temperatures.
Why Catalytic Combustion Dust Collector?
Industrial production often releases odorous gases, hydrocarbons, and fine dust that can cause severe environmental and health hazards. A Catalytic Combustion Dust Collector provides an integrated solution for pollution control and energy recovery.
Main Benefits
High purification efficiency: Oxidizes and decomposes harmful pollutants at 300–500°C, achieving >99% degradation.
Energy savings: Functions at lower combustion temperatures compared to direct thermal oxidizers.
Low maintenance: Extended catalyst lifespan and self-cleaning design.
Environmental compliance: Meets international environmental standards such as ISO and CE.
Safe and reliable: Advanced temperature control, automatic ignition, and explosion-proof design.

How It Works – Working Mechanism
The Catalytic Combustion Dust Collector operates in several key stages:
Air Intake: Polluted air (dust and VOCs) is collected and directed into the system.
Pre-filtration: Large particulates are separated to protect the catalyst layer.
Heating Zone: Air is heated using an electric or gas heater to reach activation temperature.
Catalytic Reaction Zone: Pollutants undergo oxidation on the catalyst surface, decomposing into CO₂ and H₂O.
Heat Recovery System: Extracted energy is recycled to preheat incoming air, reducing energy consumption.
Clean Air Discharge: Purified, odor-free air is released safely into the atmosphere.
